* gallium: Use enum pipe_shader_type in bind_sampler_states() (v2)Kai Wasserbäch2016-08-291-1/+1
| | | | | | | | | | | v1 → v2: - Fixed indentation (noted by Brian Paul) - Removed second assert from nouveau's switch statements (suggested by Brian Paul) Signed-off-by: Kai Wasserbäch <[email protected]> Reviewed-by: Samuel Pitoiset <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* gallium: change pipe_sampler_view::first_element/last_element -> offset/sizeMarek Olšák2016-08-171-2/+1
| | | | | | | | | | | This is required by OpenGL. Our hardware supports this. Example: Bind RGBA32F with offset = 4 bytes. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97305 Acked-by: Ilia Mirkin <[email protected]> Acked-by: Nicolai Hähnle <[email protected]>

* freedreno: fix bind_sampler_states when hwcso is NULLSerge Martin2015-12-091-0/+3
| | | | | | | | | | src/gallium/tests/trivial/compute.c expects samplers to be cleaned when the samplers list is NULL. Like in radeon, the function behave like when the number of samplers parameter is set to 0. [small s/hwsco/hwcso/ typo fix] Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx: fix texture buffers, enable offsetsIlia Mirkin2015-11-181-4/+17
| | | | | | | | | | | | | | | The main issue is that the current logic looked into cso->u.tex, which is the wrong side of the union to look into for texture buffers. While I was at it, it was easy enough to add the logic to handle offsets (first_element). - reduce texture buffer size limit (determined experimentally) - don't look at first/last levels, instead look at first/last element - include the first element offset - set offset alignment to 16 (determined experimentally) Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx: add fake RGTC support (required for GL3)Ilia Mirkin2015-11-181-1/+1
| | | | | | | | | | | | Also throw in LATC while we're at it (same exact format). This could be made more efficient by keeping a shadow compressed texture to use for returning at map time. However... it's not worth it for now... presumably compressed textures are not updated often. Lastly fix up Z32S8 transfers to non-0 layers.

* freedreno/a3xx: fix up logic for handling block formatsIlia Mirkin2015-08-171-1/+1
| | | | | | | This only appears in cubemaps which have have packed layers, so are very sensitive to any layout disagreement between sw and hw. Signed-off-by: Ilia Mirkin <[email protected]>
* freedreno/a3xx: add per-texture seamless cubemap controlIlia Mirkin2015-08-161-0/+1
| | | | | | | The default is to enable seamless cubemap filtering, but there's a bit to turn it off. Signed-off-by: Ilia Mirkin <[email protected]>
* freedreno/a3xx+a4xx: add texture buffer object supportRob Clark2015-08-121-2/+2
| | | | | | | | | Basic texture buffer support. Should be straightforward to add first/ last_element support. And with a bit of work in ir3 emulate larger texture buffer sizes. But this seems to be enough for stk gl31 render paths. Signed-off-by: Rob Clark <[email protected]>
* freedreno: remove int sampler shader variantsRob Clark2015-06-211-34/+1
| | | | | | | | We get this information from NIR (which gets it from sview decl in tgsi when translating from tgsi), so no need to maintain shader variants for this. Signed-off-by: Rob Clark <[email protected]>
* freedreno: remove tex_resourceIlia Mirkin2015-04-051-2/+0
| | | | | | | pipe_sampler_view already contains a texture, remove the redundant tex_resource member which pointed at the same thing. Signed-off-by: Ilia Mirkin <[email protected]>
* freedreno/a3xx: fix 3d texture layoutIlia Mirkin2015-03-281-2/+5
| | | | | | | | | | | | | The SZ2 field contains the layer size of a lower miplevel. It only contains 4 bits, which limits the maximum layer size it can describe. In situations where the next miplevel would be too big, the hardware appears to keep minifying the size until it hits one of that size. Unfortunately the hardware's ideas about sizes can differ from freedreno's which can still lead to issues. Minimize those by stopping to minify as soon as possible.

| | | | | | | | We need to produce a u32 destination type on integer sampling instructions, so keep that in a shader key set based on the currently-bound textures. Signed-off-by: Ilia Mirkin <[email protected]>

* freedreno: move bind_sampler_states to per-generationRob Clark2014-09-291-0/+9
| | | | | | | | | Keep the existing function as a common helper. But this lets us move an a2xx specific hack out of common code. And the PIPE_TEX_WRAP_CLAMP emulation will require an a3xx specific hack. So rather than piling on hacks, split this out. Signed-off-by: Rob Clark <[email protected]>

| | | | | | | | | | | | Still some open questions.. and at any rate, no additional piglit passes due to various wrap modes that we need to emulate in at least some cases :-( But it does fix some mystery page-faults.. So add some comments in the code where there are things that we need to emulate or do more r/e, and push as-is. Signed-off-by: Rob Clark <[email protected]>

* freedreno: add a3xx supportRob Clark2013-06-081-0/+140
The adreno a3xx GPU is found in newer snapdragon devices, such as the nexus4. The a3xx is GLESv3 and OpenCL capable, although that is not enabled yet in gallium. Compared to a2xx, it introduces an entirely new unified shader ISA, and re-shuffles all or nearly all of the registers. The good news is that (for the most part) the registers are more orthogonal, not combining unrelated state in a single register. And that there is a lot more flexibility, so we don't need to patch and re-emit the shader like we did on a2xx. The shader compiler is currently quite dumb, there would be a lot of room for improvement with an optimizing pass. Despite that, with the a320 in my nexus4 it seems to be ~2-3x faster compared to the a220 in my HP touchpad. Signed-off-by: Rob Clark <[email protected]>
